An excellent upgrade for factory L83 (5.3L) 2014+ GM trucks. Typical power gains with this intake and throttle body upgrade are approximately 10 RWHP depending on tuning in addition to notably increased throttle response. The factory L83 intake inlet and throttle body are 80mm, while the L86 intake manifold and throttle body featured in this package are 87mm.
TUNING WILL BE REQUIRED. L86 throttle body is required on L83 engines (the OEM L83 throttle body is NOT compatible with the L86 intake).
Kit Includes:
- GM L86 Intake Manifold
- GM L86 Throttle Body
- GM L86 PCV Hose Assembly
- GM L86 Throttle Body Gasket
NOTE: Intake gaskets must be reused from original intake, please be careful when removing. NOT compatible with factory L83 throttle body to inlet tube coupler. Most aftermarket cold air intake packages will include the larger 6.2L coupler.
NOTE: 2024 and later trucks use a different pinout on the throttle body and cannot use the ported L86 throttle body in this package. If you have a 2024 or newer, please shoot us an email so we can get you set up with a custom bundle.
